Data are a critical tool for understanding how COVID-19 is impacting our community. The Onondaga County Health Department is actively tracking cases in Onondaga County to identify trends as well as demographic and geographic variations in transmission and outcomes.

The data presented here represent both laboratory-confirmed cases of COVID-19 and self-reported at-home tests. At-home tests that are not self-reported are not included in these data. Many people with COVID-19 do not undergo testing, therefore these data represent only a portion of the total number of people in Onondaga County with COVID-19 infections. Please note all data presented are preliminary and subject to change as more information becomes available. Information that is not yet known or was not provided during the course of a case investigation or vaccination will be marked as “unknown.” The data are organized into the following sections:
